Xiaotie Deng got his BSc from Tsinghua University, MSc from Chinese Academy of Sciences, and PhD from Stanford University in 1989.
He is currently a chair professor at Peking University. He taught in the past at Shanghai Jiaotong University, University of Liverpool, City University of Hong Kong, and York University. Before that, he was an NSERC international fellow at Simon Fraser University. Deng's current research focuses on algorithmic game theory, with applications to Internet Economics and Finance including sponsored search auction, p2p network’s economics such as BitTorrent network, sharing economics, and blockchain. His other works cover online algorithms, parallel algorithms, and combinatorial optimization.
He is an ACM fellow for his contribution to the interface of algorithms and game theory, and an IEEE Fellow for his contributions to computing in partial information and interactive environments.

Distributed and Automated Games And Managerial Economics (daGAME) Lab
The research subjects of lab are algorithmic game theory, Internet and blockchain economics, theory of multi-agents and deep reinforcement learning. We focuses on the methodological studies for the interactions of human with agents, in the epistemological changes with respect to acquisition of data and information, equilibrium and game dynamics among human and agents, computational and communication complexity, design and analysis of algorithms and protocols. We are especially interested in applications in the Internet market design, analysis of incentives and cooperative competition, as well as high performance consensus, reputation system design, as well as cross-chain mechanism design in Blockchain economics and technology.
